At the bottom are the instructions i was following to get this somewhat antilag working. I have this on a crx and for some reason my car wont switch from the low cam map. I have the vtec disable box NOT CHECKED. i follwed all the instructions. why wont vtec activate and take me into the high cam map so my car does hit the low cam map setting for anitlag. Thanks for any help. ALso i am using the p30 map
well seeing as how the two step only builds 1-2psi and just sounds gay off the line, so did some digging over in pgmfi.org
this will only work with a p30 base
hit control K and enter the fallowing script
_rom_fill(0x58e6, 0x590d, 0x00); _rom_fill(0x6a99, 0x6ac0, 0x00);
this allows ignition timing to go to negative numbers,
also make sure vtec speed check is NOT disabled
now the slightly confusing part,
set where you want antilag in the add extra features menu
go to your low cam ignition timing and above that RPM retard ignition until it reads -6 from 0" all the way to the maximum PSI the ecu is reading
now go to your low cam fuel tables and select the same area of the map as the low ignition tables, hit CTRL + J and adjust fuel by +10-15% (play with it until you hear pop pop pop :bigok:
all you have to do is make sure your launch control is set above your vtec activation point,
EXPLANATION
when you are standing still, the car will run off ONLY the low cam map since vtec speed check is working, so it will retard timing and add fuel off the line creating a true anti-lag. however once moving the ECU will allow vtec to be activated, so you will never hit that area of the map while moving because vtec will activate and switch over to the high cam

cool

So you have a VTEC problem, not an antilag problem?

Art for the late response iv been driving around and playing with the tune. I think my high cam tune wasn't very good. So I copied my low cam maps before I changed the for the anitlag and pasted those in the high cam maps. Now the power dosent fall of like it was but there is a loose of power when I hit vtec now almost feels like it's missing a bit or leaning out. I'm going to hook my wideband back up to it tomrow I'm not sure why the tune would be no good now that it's in high cam maps?

You're scaring me.

I know I'm a very lazy tuner. I don't have a exhuast on this car to even hook the wideband to but hopefully sometime I can get some pipe and weld it up

I was thinking the same thing when I read this. :?: :-\

I know very little about tuning hondas (read alot and fucked around with my old crx ) and i would not even think this was a good idea.
